Towards collective hyperlocal contextual awareness among heterogeneous RFID systems

  8. 8. We present a mechanism for mutual discovery and the subsequent exchange of structured data among such colocated, and often heterogeneous, systems.

  13. 13. The result is what we call hyperlocal context: a digital representation of the occupants of a space at a human scale.
